Why Trapped Ion Technology?

Harmony uses an early version of IonQ’s trapped ion architecture, developed between 2018⁠–⁠2020. At launch in 2020, Harmony represented a breakthough in gate fidelity for IonQ. Beyond Harmony, IonQ’s full technical roadmap aims to deliver the full suite of trapped ion advantages below.
